Yes, you are referring to the FreeDOS Spec, from the FreeDOS Wiki: http://freedos.sourceforge.net/wiki/index.php/FreeDOS_Spec >>> *Programming languages* We prefer that all FreeDOS programs be written in either C or Assembly. Certainly all FreeDOS "Base" programs (those programs that reproduce the functionality of MS-DOS) must be written in either C or Assembly. Use of any language when writing extensions is implied, although we strongly recommend that you stick with either C or Assembly. *Programming tools* Our reference C compiler is OpenWatcom C. (Borland C 3.1 was originally chosen as the reference standard because this is the compiler used to build the FreeDOS kernel. However, it is preferable to use entirely free tools to create FreeDOS.) Our reference Assembler is NASM. (Microsoft MASM was the original reference standard because of the general availability of MASM-compatible assemblers, but NASM is now the preferred tool.) This does not mean that everyone must use these tools to contribute to FreeDOS. That would be counterproductive, as many users may prefer other programs. Rather, this means that any C code must be compilable on OpenWatcom C, and all Assembly must be assemble-able on NASM. Good programming habits such as wise use of #ifdef statements will allow you to do this. If you are working with the kernel, FreeCOM, Install, or Mem - these projects are hosted in the FreeDOS source code repository, and you should use Subversion to manage this code. <<< OpenWatcom is the reference compiler. That doesn't mean that all FreeDOS projects must be written in OpenWatcom if they are written in C, just that we prefer that C programs should compile on OpenWatcom. If you use a different compiler, that is your choice, but it would be great to be able to compile all FreeDOS programs with the same compiler. Wise use of #ifdef's will help with this. ------------------------------------------------------------------------------ _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
